Dave,
That's partial information for so hard to work with. One nice aspects about Docker is that if something complex fails, you can try something simpler. You appear to have made some assumptions here as to whether you could pile our instructions top on an existing python3 container---and "that depends". Your error messages indicate 'buster' as a release, which is not what I use in for the Rocker r-base container. So you can't just copy and paste. You could however look at Johannes backport to buster, add its repo into to your Docker setup and build that. And you can test that step by step. Good luck!
